APPENDIX B:
PRE-DEFINED PARK POSITIONS
(NORTHERN & SOUTHERN
HEMISPHERES)
The Mach2GTO does not require starting from pre-defined park positions, but it is often helpful to finish the evening in one.
Recommended:
Park 3
is a safe and balanced position.
Park 2
is a convenient position for loading and
unloading your scope.
Park 5
is a safe, low profile position with minimum cable twisting.
The scope is level on top
of the mount facing the
eastern horizon. The
counterweight shaft is
pointing down.
Both Hemispheres: RA axis is vertical, Dec = 0
The southern hemisphere
is mirror reversed.
The scope still points
to the eastern horizon,
but east is to the left
when facing the southern pole.
PARK 2
Northern
Hemisphere
Southern
Hemisphere
The scope is pointing to
the pole. The counterweight
shaft is pointing down.

PARK 3
Northern
Hemisphere
&
Southern
Hemisphere
The scope is level
on the west side of
the mount, facing
the northern horizon.
The counterweight
shaft is also level
and pointing due east.
Both Hemispheres: RA is horizontal,
North: Dec = (90-Latitude) South: Dec = (-90-Latitude)
The southern hemisphere is mirror reversed. The
scope is still level on the west side of the mount, but
is facing the southern horizon.
